Kirchhoff's First Laws or Point Law or Current Law (KCL)

 These laws are more comprehensive than ohm's law and are used for solve electrical networks

It states that:

"in any network of conductors, the algebraic sum of the current meeting at a point (or junction) is zero."

OR

"the total current leaving a junction is equal to the total current entering the junction."

Incoming currents = outgoing currents

ΣI = 0   .... at a junction
